Lmao link in comments show a 96GB a100.
Russia?
Do you have link?
i have serious doubt on authenticity of this news.
SSA800i is a very sensitive technology right now in mainland.. machine barely entered in production so nope. it could be older 90nm/65nm DUV..
iFlytek: The "Feixing-2" intelligent computing platform is under construction
iFlytek stated on the interactive platform that "Feixing-2" is a domestically-produced ultra-large-scale intelligent computing platform built by iFlytek, Huawei, and Hefei Big Data Asset Operation Co., Ltd. It is currently under construction and there is no other information to be disclosed.
Simply put, "Feixing-2" is an ultra-large-scale intelligent computing platform. It can support the rapid adaptation of various artificial intelligence models and algorithms, and improve computing efficiency through the scale effect of intelligent computing clusters.
Minsheng Securities pointed out that with the continuous growth of demand, the domestic computing power market has always been booming, especially in downstream markets such as operators and governments. This is undoubtedly a huge business opportunity, especially in the context of large operators such as China Mobile expected to purchase more than 17,000 AI servers, the relevant market demand can be said to be booming.
With the launch of Feixing-2, the discussion on AI computing power in the market will become more in-depth. In the future, the localization process of computing power is expected to accelerate, and more local companies will strengthen their own ecological construction, thereby continuously stimulating the vitality of the market.
Heyuan Gas: This year, we will accelerate the certification and introduction of electronic special gas products in the semiconductor and panel fields
Heyuan Gas said in an institutional survey that at present, all products planned in Qianjiang Electronic Special Gas Industrial Park have been completed and put into production, and the production of high-purity ammonia, high-purity hydrogen, high-purity carbon monoxide and other products is stable. Electronic-grade carbonyl sulfide, electronic-grade hydrogen chloride, and high-purity chlorine have gradually reached stable operation and mass production. The first phase of Yichang Electronic Special Gas and Functional Materials Industrial Park has been basically completed, and the planned fluorine-based, silicon-based electronic special gases and silicon-based new materials have begun trial production one after another.
The main work in 2025 is to achieve stable production and mass production of trial-produced products, gradually achieve full production and overproduction of mass-produced products, and achieve full production and sales of products. In 2024, the company has completed the introduction of all leading companies in the photovoltaic industry represented by high-purity ammonia products. In 2025, the company will accelerate the certification and introduction of electronic special gas products in the semiconductor and panel fields.
Heyuan Gas said that with the rapid growth of my country's downstream emerging industries such as semiconductors, photovoltaics, panels, and new energy batteries, the electronic special gases and silicon-based new materials products planned in the company's two major electronic special gas industrial parks are fully in line with market demand. In 2025, the company's products will be fully put into production, stable production and mass production. With the release of production capacity and product sales, the company's performance will be better demonstrated.
Shengmei Shanghai expands its products from cleaning to PECVD and other fields
The company is continuously extending its products from cleaning to fields such as PECVD to improve its product layout. The company continues to deepen cooperation with existing customers and expand new customers at home and abroad. In March 2024, the company achieved product upgrades, successfully delivered 4,000 chambers of wet equipment, and demonstrated the latest technology at the SEMICONCHINA exhibition. In May, the company launched framed wafer cleaning equipment for advanced packaging, which effectively reduced the amount of chemicals used in production and was environmentally and cost-effective. Based on its competitive advantage in cleaning equipment, the company continues to extend its products to fields such as coating and development, PECVD, and improve its product layout. In September, the company launched a new Ultra C bev-p panel edge etching equipment for fan-out panel-level packaging (FOPLP) applications. It is designed for edge etching and cleaning in copper-related processes. It can handle edge etching on the front and back of the panel at the same time, significantly improving process efficiency and product reliability.
Characterization and Control of Optical Depth of 1 Μm Nd: Yag Laser Produced Sn Plasma
Abstract
We demonstrate a method for characterizing and controlling the optical depth of Sn plasma. A pre-plasma plume is generated by the pre-pulse laser and reheated by a second laser (the main pulse), generating extreme ultraviolet (EUV) emissions. The optical depth of the EUV-emitting plasma is controlled by adjusting the delay time between the pre-pulse and the main pulse. Meanwhile, the electron density of the EUV-emitting plasma is characterized by laser interferometry. Then, the effective optical depth of the plasma is calculated via the measured electron density profile. The EUV emissivity is found to be increased with the increase of the plasma density under the same optical depth. In addition, an optically thin Sn plasma is generated by the 1 μm Nd: YAG laser and a corresponding spectral purity of 18.8% is observed. This method can be applied to balance the emissivity and spectral purity in solid-state laser-driven EUV sources for further customized applications.
